Due to the advantages of high catalytic activity,low cost and stable chemical properties,TiO2 semiconductor materials have attracted extensive attention in the field of environmental governance and energy conversion.However,TiO2 itself has a wide band gap and high catalytic activity only in the range of UV light.Moreover,the recombination rate of electron-hole pairs is high,resulting in its low utilization rate of sunlight.How to improve the utilization rate of TiO2 semiconductor materials for sunlight and promote the rapid separation of electron-hole pairs has become a research hotspot in the current field.The latest research progress of TiO2 nanomaterials was reviewed from the aspects of microstructure regulation and load modification methods,which had certain guiding significance for further improving the photocatalytic performance of TiO2 nanomaterials.
